'10 all whom "it may concern:

Be it known that I, FRANK L. O. VVADS- WORTH, I of Sewickley, Allegheny county, Pennsylvania, have invented a new and useful Glass Storage-Battery Case, of which, the following is a. full, clear, and exact description, reference being had to the accompanying drawing, which shows in sectional plan view storage battery cinbodying my invention.

My invention relates to a lining for storage battery cases formed of glass and hcving integral projections on the inner surface forming devices for holding end. spncing the battery-grids or elements. A battery thus constructed is of great advantage, for it extremely simple in its construction, it enables the battery elements to be spaced apart effectively without tyinig; them together, and all the parts of the. lining being made of glass, it affords the most favorable conditions for receiving and holding the battery elements and the liquid.

In the drawing 2 represents the battery case provided with a lining composed of glass slabs or plates 3 having integral parallel gridoizpertitimi supports 4. Some of the plates have projecting margins 5 so that they will make a. tight joint. ".he plates w 10h are provided with theseprojccting margins are preferably those on which the supports 4-, l are formed, and they are fitted against plain plates 3 cs shown. The supports may extend to and be made integral at least one of the marginal projec- .s, since in this Way the strongestposconstruction secured. The projecon the glass plate or slahs are preterchiy formed by rolling a mass of glass into a sheet and then bringing upon the some :1 die v; ch by forcible pressure molds the projec tions thereon. lhis gives plate which is free from internal aims and which has characteristicswhich enable it to withstand changes of temperatures which would crack the ordinary plate made by a. pressing operct-ion alone. Such changes of temperature are frequently met with in batteries, this not only to the heat generated in. mixing the battery fluids, but also to the passage of heavy currents. The parts of the lining are secured together and the storage battery grids or elements 6 are placed between the supports l and are held thereby in vertical position.

The ribs or supports l are preferably of trapezoidal form in cross section, (18 shown, thus giving the battery elements clearance in the intervening grooves. This not only prevents sticking the el z-nients or grids and facilitates their removal and insertion out also relieves strains due to buckling of the elements. I

The form of the projections and the mar; ginal form of the plates may he changed, since lVhnt 1 claim is:'-.

1. A storage battery cell hering therein at opposite sides separate sheets of glass hav ing each a plurality of parallel rihs pressed therein, said. rihs being of thickness at their outer edges than at t3 bases; schstentinlly as described. A

A. storage battery cell having therein at opposite sides separate sheets of glass,

each formed in one integral piec'end having each a plurality of parallel rilos therein, said ribs or supports heing oi trapezoidal form in cross section, substantially as described.

In testimony whereof, I- have. hereunto set my hand.
